United Utilities are refusing to lift the hosepipe ban in Hyndburn - despite heavy rain over the past month.
Since the hosepipe ban was introduced in June customers across the North West have saved 3.3 billion litres – the equivalent of 16 baths worth per household.
But reservoirs in the Pennines are still only 54 per cent overall, compared to 68 per cent in a typical year.
Dr. Richard Blackwell, United Utilities’ supply demand manager, said: "We are very grateful to our customers for their continuing efforts to save water. After the rain over the last few weeks it is easy to forget that the first seven months of the year were the driest since our records began.
"All the rain we’ve had has definitely made a difference and generally our reservoirs are in a much healthier state, apart from those in the Pennines. To ease the pressure on our Pennine sources and help them recover more quickly we are using our integrated pipe network to bring in more water from Cumbria and North Wales.
"We will lift the hosepipe ban as soon as we can, when the reservoirs have recovered to a point where we are sure their storage will meet the needs of the North West."
